6.6.10 Selecting the Measurement Trigger Source

The trigger system is waiting for a trigger signal in the Initiated state. Before you generate a

trigger, you must select a trigger source. To select the SYNC Trigger to start the

measurement at specific phase angles in the waveform:

TRIGger:ACQuire:SOURce SYNC

TRIGger:SYNC:SOUR PHAS

TRIGger:SYNC:PHASE 0

To select IEEE-488 bus triggers (group execute trigger, device trigger, or *TRG command),

use:

TRIGger:ACQuire:SOURce BUS

To select the signal driving the Trigger Out from the transient, use:

TRIGger:ACQuire:SOURce TTLTrg

6.6.11

Generating Measurement Triggers

Providing that you have specified the appropriate trigger source, you can generate triggers

as follows:

• By sending one of the following over the IEEE-488:

• TRIGger:ACQuire:IMMediate

• *TRG

• a group execute trigger (GET)

• By waiting for a specific phase angle of the waveform

• By generating an output transient that causes the Trig Out to output a pulse.

• By pressing the front panel START soft key in the HARMONICS/WAVEFORM when the

unit is operating in local mode.
